Multi-Cooker + Stir Tower

Alex Clayton's UX design work on the KitchenAid Multi-Cooker and Stir Tower.




2013 — 2015





The KitchenAid Multi-Cooker + Stir Tower is an enhanced slow cooker that has ten cooking modes with a maximum temperature of 450°F for searing. The Stir Tower is an accessory that attaches to the Multi-Cooker and provides automatic stirring with three continuous speeds and two intermittent modes.

I joined the project about halfway through as the lead UX Designer. Some initial industrial design and user interface concepts already existed and I carried the project through to production.


Since some work had already been started up front, most of the initial work for me was coordinating with the marketer on feature requirements and understanding existing multi-cookers on the market.





MC+ST Modes and Temps

I began working with the engineer and industrial designer to build in the feature requirements and iterate on the information architecture of the user interface.  Knowing the cook modes, temperatures, and times helped me organize the content.


Throughout this process, I developed the behavior specification that details exactly how the the product should function in every possible scenario. Below is a portion from the section on adjusting the temperature and how the screen should respond to the buttons.

After refining these elements, I conducted several usability studies around the user interface and ergonomics of both the Multi-Cooker and Stir Tower using functional prototypes. While we found many things that worked well, there were areas for improvement.

Some of the key areas that needed improvement were adding more clarity to the UI when it finished preheating, being able to skip forwards or go backwards in guided modes, and the max fill line was too high on the bowl causing food to spill over.


Working with the team, I was able to translate these research insights into design improvements to finalize the product and get it into production.
